Thanks for the reply and the information on the gpu resistance.

I'll try what you mentioned in the next days and I'll update, I really hope I have not broken the edp cable, or worse connector, I've been very careful with it.

Here's a picture of the soldering made on the power connector, it is a bit rough since is my second dime soldering on a board, the small pin in the center looks shorted to positive but is not...

Hello, here's more details on the board:

G531GW REV 1.5

I started checking the board and found that with power plugged in the main coils (8v, 5v and 3,3v) seems to carry the correct voltage, same goes for the CPU coils.

GPU side things do not look good. I get 0ohm on all the inductors, what can I check next?

on a side note I noticed that the first mosfet after the power plug has a deep scratch on the top surface (see pic), I must have damaged it while removing the old power plug, checking source and drain in diode mode gives the same value of...

Hello everybody, I replaced the power plug of my Asus G731GW-EV123T (i7 9750h - 16gb - RTX2070) because the plug would overheat if not kept pressed in with a finger.

After soldering the new connector and checking for shorts on the soldered feet the pc has a new problem.

The pc starts up as soon as i plug the power, even if I disconnect the power button, but i get no video signal and after a while it turns off.

Where can I start troubleshooting?

Thanks

you're right sorry, in the hurry of the moment I didn't consider what i read. I'm in the first steps of learning...

yesterday I must have fumbled while taking the measurements, today I took the time to take the measurements and the result is that all the cpu's coils read 2ohm while all the gpu's coils look shorted.

Next step would be to remove all the coils to locate the short right?

thanks for the reply, I'm looking around for the schematic of this particular revision, for now i found only older or newer models

here's the values, how come the reading takes a while? is if because of the capacitors in the circuit?

cpu's coils read were all between 2 and 0.2 ohmthanks for the reply, I'm looking around for the schematic of this particular revision, for now i found only older or newer models

​Hello, I acquired a not working ASUS ROG SCAR GL504G (i7 8750H-RTX 2070 8gb GL504GW rev 4.1) to try to try to repair it and learn something new.

The laptop didn't want to turn on, while testing removing components it turned on for a couple of seconds but after that no more signs of life. I cleaned and inspected the board and found some tiny solder spheres rolling around, maybe signs that someone already tried to work on it. The other thing i found was a pair of stripped solder joints where there should have been what from the images I found online I think is a fuse, I am now trying...

Hello everybody, I write from Italy, i am a matalworker technician that loves to fix things. I've joined the forum because in proved very useful in the first steps of learning new things about electronics
